逆向行駛 最愛的最殘酷、最美的最虛無
有時候會碰到有些東西臨時要搬移，檔案又是幾百GB，這個時候該怎辦咧! 有位好心人Phil Howard寫了一個resend.sh檔案方便有同樣困擾的人使用，不用設定RSYNC，用完即丟，服用本藥品可說是完全的無感啊 ?
Step.1：發送端與接收端都先安裝RSYNC與SCREEN，在SCREEN模式底下做傳輸的好處是不怕斷線就要從頭再來，就算是跑個幾百TB，生性的義薄雲天SCREEN兄弟會幫你跑完任務的 ?
yum install -y rsync screen
*********使用前要關閉傳輸端雙方的防火牆*********
Step.2：首先在要搬家的A主機操作，先進入SCREEN模式然後切換到要搬移的位置
screen -R
cd /web/www/qoo
wget http://acelnmp.googlecode.com/files/rsend.sh
chmod +x rsend.sh
rsend.sh
此時螢幕上會出現三排指令，摳比第一行以IP位置顯示的指令然後切換到要接收檔案的B主機
Step.3：SSH登入要接收檔案的B主機，一樣先進入SCREEN模式然後切換到A主機搬家過來的位置
screen -R
cd /web/www/qoo_backup
把剛剛從A主機利用rsend.sh產生的第一行指令摳比過來貼到B主機的SSH運行
rsync -aHvz rsync://8.8.8.8:26736/. .
這個指令是rsend.sh幫你產生的，在B主機一執行就開始刷刷刷的傳檔囉!
傳送完畢後輸入EXIT退出SCREEN模式，回到A主機按CTRL+C停止RSYNC，就這樣~ 免背RSYNC指令，真正的無痛搬家。 ?
